THE FORD LUBRICATING SYSTEM
The purpose of lubrication is to reduce friction between
moving surfaces. The oiling chart shown on pages 26-27 gives full
information for lubricating the Ford car. Proper lubricating
has a vital effect on the life of your car; consequently you should
follow these instructions very carefully.
Engine Lubrication
All parts of the engine are lubricated from the oil reservoir
in the oil pan by the Ford Pump, Splash and Gravity Feed.
Only high grade engine oil should be used in the engine.
Oil of this kind reaches the bearing surfaces with greater ease
and cuts down frictional heat.
It should have sufficient body so
that the pressure between the two bearing surfaces will not
force out the oil and a11ow the metal to come in actual contact.
Inferior oils have a tendency to carbonize quidoy, also ''gum
up" the piston rings, valve stems and bearings. In cold weather
a light grade of oi] having a low cold test is absolutely essential
for the proper lubrication of the car.
Draining the Oil Pan
It is advisable to clean out the oil pan by draining off the
old oil when the new car has been driven five hundred miles,
and thereafter to repeat this operation every 500 miles. The
oi1 should be warm before draining.
Lubricating the Differential
Every 5000 miles the lubricant in the differential should be
drained and the housing flushed with kerosene. New lubricant
should then be added until it reaches the level of the oil filler
hole in the housing.
Lubricating the Transmission
About once every five thousand miles the gear lubricant
should be drained from the transmission by removing the drain
plug at bottom of transmission case. The interior of the trans-
mission case should then be thoroughly flushed with kerosene
and refilled with fresh gear lubricant.
The new lubricant is poured into the transmission through
the filler hole, located at the right hand side of the transmission
case. Pour sufficient lubricant in until it reaches the level of
the filler hole.
